Abstract

The route to chaos through type I intermittency is observed in a gain-modulated cw CO₂ laser at a low frequency, 120 Hz. As the current is decreased, the output follows the pattern quasi-periodicity → type I intermittency → chaos → laser off. We characterize the chaos by obtaining the Kolmogorov entropy and prove that the pattern is caused by the unstable discharges.
